Low noise aeration apparatus for seawater recovery after desulphurization

Abstract

The invention relates to a low noise aeration device for recovering seawater after desulfurization, which comprises an aeration pool, an aeration blower and an aeration pipe net, wherein the aeration pipe net comprises an aeration wind chamber and a plurality of aeration wind pipes connected in parallel, each aeration wind pipe is provided with aeration pores evenly distributed and is vertical to the direction of water flow, and the aeration wind pipes stretch downwards along the inner wall of the aeration pool respectively and are arranged in parallel on a base plate of the aeration pool. The device has the advantages: due to the cancel of the connected main pipes, the aeration wind pipes stretch downwards along the inner wall of the aeration pool and are arranged under water directly; and compared with spreading noise in the air, the spreading noise in the water is greatly reduced, so that the pollution to the environment cause by working noise is also reduced. The aeration devise has simple manufacture and installation and the reduced cost, and can be widely applied to a wet method fuel gas desulfurization device and has higher practical value.

Description

technical field [0001] The invention relates to wet flue gas desulfurization equipment, in particular to a low-noise aeration device for recovering seawater after desulfurization. Background technique [0002] At present, the combustion flue gas of coal-fired industrial boilers or power plant boilers contains a large amount of SO 2 Acidic pollutants such as acid pollutants have brought more and more serious environmental pollution problems to people, and are the main causes of air pollution and acid rain. With the development of science and technology, in order to solve the above problems, a flue gas seawater desulfurization process has emerged. In the flue gas seawater desulfurization process, the seawater recovery system needs to use the means of aeration and oxidation recovery to make the seawater discharge up to the standard. Most of the projects that have been put into production in China use fans and aeration heads. Because the aeration head is complicated to make, a...

Problems solved by technology

Most of the projects that have been put into production in China use fans and aeration heads. Because the aeration head is complicated to make, and at the same time, the aeration head needs to use a main pipe. Both the aeration head and the main pipe are arranged on the water surface, and the working noise is particularly loud. , usually above 85 decibels, thus bringing new environmental pollution
